Nrrn TATES WILLIAM C. CHASTAIN, OF REPUBLIC, MISSOURI.

THRESHOLD.

SPECIFICATION forming part of Letters Patent no. 635,656, dated October24, 1899.

Application filed April 3, 1899. Serial No. 711 623. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM G. CHASTAIN, a citizen of the United States,residing at Republic, in the county of Greene and State of Missouri,have invented a certain new and useful Threshold to be Made of Metal, ofwhich the following is a specification.

This invention relates to thresholds, and more particularly to thatclass adapted to be formed of metal; and the object of the invention isto provide a construction in which the rain which would ordinarily enterbeneath the door will be stopped and drained from the threshold.

A further object of the invention is to provide a simple and cheapconstruction which will be readily applied to a doorway and. which willbe efiective in its operation;

In the drawings forming a portion of this specification, and inwhichlike numerals of reference indicate similar parts in the severalviews, Figure 1 is a plan view of a threshold. Fig. 2 is an outside viewof the edge of the threshold. Fig. 3 is an end View of the threshold,and Fig. 4 is a section on the line 4 4 of Fig. 1.

Referring now to the drawings, the threshold consists of a metallicplate 5, the inner edge of which is beveled in the usual manner, asshown at 6, while the outer edge 7 has a,

much steeper bevel, the top 8 of the plate be-' ing parallel with thebottom 9. In the top of the plate and spaced from the angle of the topand the edge 6 is formed a groove 20, having a series of recesses orpassages 9 formed in its bottom and which extend downwardly into theplate and then forwardly and through the outer edge 7 thereon, theoutlet-openings for these passages being shown at 10. The openings ofthe passages 9 into the groove 20 are separated by webs 11, the bottomof the groove adjacent the end openings being slanted downwardly, asshown at 12.

In the upper surface of the plate 5, intermediate the groove 20 and theouter edge 7 of the plate, is formed a second series of openings orpassages 13, communicating with the horizontal portions of the passages9, additional passages 14 being formed one at each end of the plate andcontinuing downwardly and then outwardly through the edge 7 of thelatter, these openings 14 being continued longitudinally and through theends of the plate, as shown.

Upon the upper surface of the plate 5 and intermediate the openings 13and the edge 7 is formed a bead 15.

In applying the threshold the edge 6 is dis posed inwardly and the edge7 disposed outwardly, the head 15 being engaged by the door when closed.Thus if water attempts to enter beneath the door the groove 20 willprevent its passage over the threshold, and instead it will enter theopenings 9 and 13 and will be drained through the outlets 10.

It will of course be understood that the plate may be made of anydesired material and may be cast or otherwise formed, and it will beseen that the head 15 may have any desired height and that the openingsmay have any desired dimensions.

What I claim is A threshold consisting of a plate having beveled innerand outer edges, a bead upon the upper surface of the plate adjacent theouter edge, a series of openings in the upper surface of the plate andpassing downwardly and outwardly through the outer edge thereof andunder the head, the end openings of the series being continued throughthe ends of the plate, and a second series of openings in the rear ofthe first-named series and passing downwardly and outwardly andcommunicating with the first-named openings, the upper surface of theplate being grooved in alinement with the last-named series of openingsintermediate the end openings of said series and the ends of the plate,said grooves slant ing downwardly at their inner ends.
